APPARATUS FOR VOLAT-IIL'IZING DISINFECTANTS.

SPECIFICATION forming part of Letters Patent NO. 654,946, dated-July 31, 1900.

Application filed October 2'7, 199 9.

To all whom, it may concern.-

Be it known that I, VINoENzo CERvELLo, professor, a subject of the King of Italy, re-

the Kingdom of Italy, have invented certain new and useful Improvements in Apparatus for Volatilizing Medicaments, Disinfectants, and the Like, of which the followingis a specification. V

The apparatus forming the subject of this invention is designed to impregnate the air in living-rooms with vapors in definite proportions of such medicaments, disinfectants, and the like as are capable of volatilizing, either from the solid or from the liquid state, at a temperature not exceeding 100 centigrade. The capability of the apparatus to impregnate to any desired degree is due to the medicaments being volatilized by contact with a surface heated by steam at atmospheric pressure that is, at a practically constant temperature-so that a definite quantity of a certain medicament develops a definite amount of vapor within a certain defi-' nite time. If the cubical capacity of a room has been ascertained, it will be an easy matter by the aid of this apparatus to'distribute ized medicament Furthermore, the operation of the apparatus is such as to enable it to work for several hours without any attention to it, providing means are provided for returning the steam which heats the walls of the apparatus in a condensed form without allowing the condensation-water to come into contact with the medicaments requiring to be volatilized.

Referring to the accompanying drawings, Figure 1 shows a side elevation of one form of my apparatus. Fig. 2 is a plan thereof, and Fig. 3 is a longitudinal vertical section of the apparatus,

The casing (it, provided with a handle I), is formed with air-holes g h, and with afront opening f for the introduction of the spiritlamp 0. The lamp is arranged to burn for several hours and has two wiclgs or a duplex burner d and e, operated by spindles (I and The u or ortion of the casin or contains P P o the water-boiler 11, having a flat top plate j,

lwhich is heated from below. The top platej is formed with a centrally-arranged dome is,

closed at top by a rubber stopper 1. Through the said stoppera thin glass pipe m is introduced, the lower end of which never dips into the water of the boiler 41 and which extends upward so far (to sixty centimeters and more) as to cause, as before mentioned, the steam to condense inside this pipe, and finally return into the boiler without wetting the outside of the pipe m. The substance or substances to be vaporized is or are placed upon the plate j and is or are distributed in the various sectors 0, surrounding the dome is and limited by the spider-ring n.

The apparatusis used in the following man ner: First, the boiler is filled with water to about eight to nine tenths of its capacity, whereupon the stopper Z is inserted into the opening of the dome it, taking care that the lower end of the pipe m does not descend into the water. Then the ring or is placed around the dome k, and the proper quantity of the substance or substances for volatization is or are distributed over the plate j, within the sectors of the ring at. The two wicks (land 6 are then lighted and allowed to burn until the water is brought to boiling, after which one of the flames is extinguished and the other lowered so far as to keep the water just boiling until the substance or substances are completely volatilized.

I claim 1. In an apparatus of the character described, a casing, heating means, a boiler with a dome above the same, means for supporting the medicament above the boiler, and a vertical pipe extending through the dome and into the boiler independent of the medicament and to a distance above the same to condense the steam within the pipe and to prevent the same from commingling with the volatilized medicament. g

2. In an apparatus for the purpose described, a casing, heating means, a boiler, a

dome extending upward therefrom, a sealing device for the upper end of the dome, means for supporting a medicament above the boiler and around the dome independent of the medicament and its holder, and a long ver tical pipe extending into the boiler and up ward throughthe dome-t0 condense the steam suflioient to condense the steam within the in said;pipe. and keep it from contact Withthe pipe and return it to the boiler without wetvolatilized medicament. r ting the exterior of the said pipe. 1 3.
